How high are you talking. My husband had the meter say ketones and refused to go to the hospital. His sister had just had breast surgery and we were all together talking. He move away and stayed with the kids watching tv and it came down within minutes.
Another time he hit 33 on the meter and wouldn't go to er. It came down eventually.
He was running extremlt high for a number of years since he refused to take meds.
He lost 50 pounds in a few months. He said it was healthier to lose the waight but he looked like someone from a concentration camp even though he weighed 150 pounds. Last October he had a heart attck and we were told since he was so high in the blood sugars for so long, all the nutrients he was peeing out and his body was feeding on his mucles. He had a painless heart attack with some diabetics can have.
Hope you take care of yourself.
